Convert WMI Win32_OperatingSystem InstallDate to mm/dd/yyyy format (C# - WPF)

Question

Hi,

I am wondering how you would convert the date and time from 20100131022308.000000-360.

I've been trying to figure it out for a while now and I can't seem to get anywhere.

I am using C# in a WPF Application.

Answer 1

Ignore everything after the period:

string date = "20100131022308.000000-360";
date = date.Substring(0, date.IndexOf('.'));
DateTime actualDate = DateTime.ParseExact(date, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);
Console.WriteLine(actualDate);

It's a pretty straightforward date format.

Answer 2

The System.Management.ManagementDateTimeConverter class was made to solve your problem. Use its ToDateTime() method. It properly parses milliseconds and the UTC offset in the string:

  DateTime dt = System.Management.ManagementDateTimeConverter.ToDateTime("20100131022308.000000-360");
  Console.WriteLine(dt);

Output: 1/31/2010 2:23:08 AM
